Jonathan Papelbon’s four-year contract with the Phillies is now official, as the team announced the deal along with one little twist: He’ll get $50,000,058.

That extra 58 bucks matches his uniform number, which he’ll apparently be taking from new bullpen-mate Antonio Bastardo.

Papelbon’s contract also includes a $13 million option for 2016 that vests if he has 55 games finished in 2015 or a total of 100 games finished between 2014 and 2015. In other words, if he stays healthy and remains a closer it would become a five-year, $63 million deal. Wow.

Philadelphia gives up its first-round pick to sign Papelbon away from Boston, but the Phillies will likely get another team’s first-rounder (and a supplemental first-rounder) when Ryan Madson signs elsewhere.

Buchholz, 33, was acquired by the Phillies from the Red Sox in December 2016, but he made only two starts before an MRI revealed he had a partial tear of his right flexor pronator mass. He underwent surgery in April and missed the rest of the season.
